I have a Logitech Optical Wheelmouse and it is not detected correctly in
2.5.12-dj1. It is detected as a 'PS/2 Logitech Mouse on isa0060/serio1' and
the scrollwheel does not work.

when I let the detection function print the devicetype I discovered that the
devicetype of my mouse is not listed in the logitech_{4btn,wheel,ps2pp}
arrays (it is 86).

when I put 86 in logitech_wheel[] it is still listed as 'PS/2 Logitech Mouse
on isa0060/serio1'

when I also put 86 in logitech_ps2pp it is listed as 'ImExPS/2 Microsoft
IntelliMouse Explorer on isa0060/serio1'....

It appears that it is not recognised in the if statement on line 405,
printing the numbers in the param[] array gives:
param[0] = 8
param[1] = 0
param[2] = 0
param[3] = 205
param[4] = 246

In every combination of 86 in the logitch_* arrays I get the following
messages when I use the wheel:
psmouse.c: Lost synchronization, throwing X bytes away. (with X = 1-3)
the mouse does not work correctly for PSMOUSE_{IMPS,IMEX} otherwise the mouse
and the three buttons work ok.

I do not know what to do next, but I want to use my scrollwheel!!
BTW the wheel works in 2.4.x
